I was wondering what you guys thought of Valvoline Synpower Synthetic Oil, its buy one get one free at my work and i was thinking of picking some of it up for my next oil change. im running 0-40 Mobile 1 right now would 5-30 synpower be sufficient. I would like to get some opinions on this before i go and run it....if theres bad experiences i wont even bother. Thanks

 

i used it in the beginning and it worked fine.. after all my friends told me about royal purple i just switched over with them ... we would buy multiple cases at local tuner shop and get a discount. so its all good.
